#### Chapter Problems:

 9.5.1: There are three unknown circuit elements connected to a voltage source as shown.  The voltage is controlled by the slider and given in Volts. 9.5.2: An oscilloscope is connected to a sine ac supply voltage as shown above. By clicking in the graph window, you can read the voltage values. 9.5.3:  There is a resistor in a  circuit connected to a voltage source as shown.  The voltage is controlled by the slider and given in Volts. 9.5.4: An unknown resistor is connected to an AC voltage source as shown.  The rms source voltage is controlled by the slider.  You can click-drag inside the graph to measure coordinates. 9.5.5: The circuit is an RC circuit with a capacitance of  0.30mF. The graph displays current vs. time. You may read values from the graph clicking the mouse anywhere on the graph 9.5.6: The circuit with a battery, an inductor and a 20 Ohm resistor can have a battery connected or disconnected depending on which switch is open. 9.5.7: The circuit with an inductor and an initially charged 2mF capacitor, evolves in time. You may determine the current from the graph. 9.5.8: The circuit with an inductor, a 3.0 Ohm resistor, and an initially charged 4.8 mF capacitor, evolves in time. You may look at the charge on the capacitor from the graph. 9.5.9: An unknown circuit element is connected to an AC voltage source as shown. 9.5.10: Find the resonant frequency of the LRC circuit.
